A J-type nut is a type of fastener that is shaped like the letter "J." It is designed to be used in applications where a threaded anchor point is needed on a flat surface, similar to U-type nuts. J-type nuts are commonly used to secure or fasten components to sheet metal, panels, or other thin materials.
J-type nuts, like U-type nuts, are often used in applications where a threaded connection needs to be established on a flat or thin material without requiring access to the backside of the material. They are commonly used in industries such as automotive, electronics, appliance manufacturing, and general metalworking.
